您是公司的網(wǎng)絡(luò)管理員。現(xiàn)在公司購(gòu)買了兩臺(tái)華為的S5700系列的交換機(jī)，為了提高交換機(jī)之間鏈路帶寬以及可靠性，您需要在交換機(jī)上配置鏈路聚合功能。

?

操作步驟

?

步驟一?以太網(wǎng)交換機(jī)基礎(chǔ)配置

華為交換機(jī)接口默認(rèn)開啟了自協(xié)商功能。

首先修改交換機(jī)的設(shè)備名稱，然后查看SW1上G0/0/9和G0/0/10接口的詳細(xì)信息。

步驟二?配置手動(dòng)模式的鏈路聚合

• ?

在SW1和SW2上創(chuàng)建Eth-Trunk 1，然后將G0/0/9和G0/0/10接口加入Eth-Trunk 1（注意：將接口加入Eth-Trunk前需確認(rèn)成員接口下沒有任何配置）。[SW1]interface Eth-Trunk 1[SW1-Eth-Trunk1]quit[SW1]interface GigabitEthernet 0/0/9[SW1-GigabitEthernet0/0/9]eth-trunk 1[SW1-GigabitEthernet0/0/9]quit[SW1]interface GigabitEthernet 0/0/10[SW1-GigabitEthernet0/0/10]eth-trunk 1[SW2]interface Eth-Trunk 1[SW2-Eth-Trunk1]quit[SW2]interface GigabitEthernet 0/0/9[SW2-GigabitEthernet0/0/9]eth-trunk 1[SW2-GigabitEthernet0/0/9]quit[SW2]interface GigabitEthernet 0/0/10[SW2-GigabitEthernet0/0/10]eth-trunk 1驗(yàn)證Eth-Trunk的配置結(jié)果。[SW1]display eth-trunk 1Eth-Trunk1's state information is:WorkingMode: NORMAL Hash arithmetic: According to SIP-XOR-DIP Least Active-linknumber: 1 Max Bandwidth-affected-linknumber: 8 Operate status: up Number Of Up Port In Trunk: 2 ----------------------------------------------------------------------------PortName Status WeightGigabitEthernet0/0/9 Up 1 GigabitEthernet0/0/10 Up 1 [SW2]display eth-trunk 1Eth-Trunk1's state information is:WorkingMode: NORMAL Hash arithmetic: According to SIP-XOR-DIP Least Active-linknumber: 1 Max Bandwidth-affected-linknumber: 8 Operate status: up Number Of Up Port In Trunk: 2 ----------------------------------------------------------------------------PortName Status WeightGigabitEthernet0/0/9 Up 1 GigabitEthernet0/0/10 Up 1

回顯信息中灰色陰影標(biāo)注的部分表明Eth-Trunk工作正常，成員接口都已正確加入。
